' To a/ Z whom it may concern:

' Be it known that we, CHARLES HIBBARD and WARRENHIBBARD, citizens of the United States, and residents of Sandyhill, in the county of Washington and State of New York, have invented a new and Improved A Vaporizer, of which the following is a full,

clear, and exact description.

The invention relates to explosion-engines and its object is to provide a new and im proved vaporizer or mixin -valve arranged to insure a quick and comp ete vaporization of the liquid fuel (gasolene) Vand an intimate mixture of the proper amount .of air and vaporand to preventflooding of the device by the liquid `fuel and frosting of the liquid-fuel chamber in cold weather.

The Iinventior'i consists of'novel features and arts and combinations of the same, as

will. e more fully described hereinafter and then pointed out inthe claims.

y A. practical embodiment of the Vinvention is ,l spending partsin all lthe views.

Fig. ZVis-atransverse section of the same on the line 2 2 of Fig.V 3. Fig. 3 is a sectional plan Fig. 4 is a like view of the saine on the line 4 lof Fig. 1. In the casing A of the 'vaporizer are formed an airehamber'B and a mixing-chamber C, connectedvvith 'each other by a. valve-port controlled by an air-valve E, ada ted to be seated yon the valve-seat D, anl centrally within the said air-chamber B is secured a l Vvessel F for containin gasolene or other liquidfuel, the said vesse bein connected at its y bottom byan outletGWith t e mixin -cham 4 ber C, the terminal of the said outlet orming a valve-seat G', normally closed by theliquid-fuel valve H. The air-valve E is in the form .of a ring-shaped leather valve secured to av metal body E', having a stern E2 mounted! to slide vertically Lina' bearing formed on thetbottorn cap A of the casing A, the said body-E being pressed on by a spring E3, seateil'onthe'ca A! and serving to normally hold the'valve to its seat D. The liquid-fuel valveH is in'the forni of a cu shaped metal- Specification of Letters Patent.

The liquid fueb omen overheadesupply by l Way of a supply-pipe J 4to an inlet K, opening into the bottom of the vessel F\, .the said inlet K being partly' formed in` the'casing yA and partly in the bottom of the vesselF, and the s'aidjnlet K is controlled by avalve L, hav#l ingits valve-stemLl attached toa lloat L and located Within the vesselF and rising and fallin therein with theli uid fuel inthe said Vvessie it being understoo that when` the liquid fuel falls below. a, redetermined level thenthe -iloat sinks and t e valve Lis opened to admit liquid to the vessel F, and when the liquid risesln the vessel and reaches the prede'- v s.

` The air-chamber B is provided in its sideV Wall with inlet-openings B and BZ, of which the inlet-.opening B may be connected by a pipe N with any suitable Warm-air supply, so as to permit warm airI to pass into the said chamber B. The other opening .B2 leads to theatmosphere, andthesald openings-B and Y .i working cham ton thereof is on t ing so the valve-H is C, the said valve E short distance carrying the liquid-fuel Vvalve H along,

e side Wall of the mixing-chamber C is provided with an outlet-opening C', connected by a pipe P with the Working chamber ofthe explosion-engine, so that when the device is in use on the ex losion-engine andthe pise suction-stroke then the valve'E' is caused tofmove'downward against the tension of its spring E3, so as to connect the air-chamber B with the mixing-chamber after being opened' a so as to openl the outlet G to permit g'asolene or like liquid fuel to flow from the vessel F ont-o the top of the open valve H fo'r' the air from the chamber B to vaporize vthesaid gasolene and to carry the same along d'ownintov the chamber C, from which the mixture can ass by the pipe P into the `er of the engine. At the end of the suction-stroke of the piston the valve 3 returns the valve E to its seat, and in domoved by its spring H3 immediately revious to the finally seate on its valveonto its seat G valve E being vseat D.

the liquid fuel into the mixing-chamber C does not begin until after thel valve E is opened, and the iioW of the liquidlis cut ofll previous to the valve E moving back to its seat, so that an possible flooding of the vaporizerby the iquid fuel is completely prevented.

By having the vessel F containing the liquid fuel surrounded by the chamber B it 1s evident that the said vessel F is externally warmed b the entering Warm air to prevent frosting o the saidv vessel -F gasolene contained therein, and consequently V-a proper andqui'ck vaporization of the li uid W en -used in connection engine W1th one valplorizer for each cylinder- `of the engine, 1n

fuel takes place Whenever the valve opened, as previousl explained'.

In case 'any liquid uel 1s not vaporized and passes into the mixing-chamber C it settles in an annular recessA, formed on the upper faceof the cap A, and' from-the bottom of this recess A3 leads a vipe Q, discharging into the top of the vessel so that the said nonvaporizedliquid fuel is forced back into the vessel F whenever the piston in the cylinder of the engine is on the return stroke. This arrangement for forcing the non-vaporized li uid fuel back intothe vessel .F is valuable with the two-cycle W ch case there would be no check-valve betweenthe vaporizer and -`mixing-chamber or crank-case of the engine.

and chilling of the' vand having an outlet,

It is understood that the iioat L fits suificiently loosely in the vessel F to allow the liquid forced back by Way ofthe pipe Q to mix with the liquid contained in the said vessel.
